Science riddle lock

A science riddle with the answer gravity, typed into a written-answer lock: the force that pulls the apple down, keeps your feet on the floor and holds the Moon around the Earth.

The template is free: it publishes as it is on the free plan, players open a link without signing up, and the lock never expires.

Questions about this template

What is a science riddle whose answer is gravity?
I pull the apple off the branch, I keep your feet on the floor and the Moon circling the Earth, and on the Moon I am six times weaker than here: gravity. The hint adds Newton and the first letter, so pupils from about ten can find it without help.
Can I turn it into a science escape room?
Yes. Rewrite the riddle and the answer for any idea of your syllabus, a state of matter, a planet, an organ, a chemical element, and chain several locks so each answer opens the next. Keep each answer to one word so pupils cannot spell it three ways.
Is this science riddle lock free?
Yes. It is a basic lock with a riddle, a hint, your own wrong-answer line and a designed reveal showing 9.8 m/s². A free account publishes it as it is, players need no account, and it never expires.
Is this template free?

Can I change the answers and the texts?

What do players need?
A phone or a computer with a browser. They open your link or scan your QR code, and never create an account.
How long does it take to play?
About 5 minutes, from the first lock to the reward.
